POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category II (output, transient voltage 2500V)
and Installation Category II (transient voltage 2500V).
Basic insulation (signal input to output to power input:
300V) is maintained. Prior to installation, check that the
insulation class of this unit satisfies the system require-
ments.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 120V AC rating: 85 – 132V, 47 – 66 Hz, approx. 3VA
200 – 240V AC rating: 170 – 264V, 47 – 66 Hz, approx. 3VA
■GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

INSTRUCTION MANUAL

INSTALLATION
Detach the yellow clamps located at the top and bottom of
the unit for separate the body from the base socket.

DIN Rail Adaptor
Shape and size of the base socket
are slightly different with various
socket types.
■DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bot-
tom. Hang the upper hook at
the rear side of base socket on
the DIN rail and push in the
lower. When removing the
socket, push down the DIN
rail adaptor utilizing a minus
screwdriver and pull.
■WALL MOUNTING
Refer to “EXTERNAL DI-
MENSIONS.”
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram on the top of the unit.
When an input resistor is provided with the module, attach it together with input wiring to the input screw terminals.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 380V
AC/120VA or 125V DC/30W at the maximum (≤ 0.5A for
CE marking). For use with inductive load, external pro-
tection is recommended.

ADJUSTMENT PROCEDURE
■HOW TO ADJUST ALARM SETPOINTS
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) Turn the front dial to an approximate position for the
setpoint.
2) Vary simulated input signal around the setpoint and con-
firm relay operation and set.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Setpoint
Increase the input signal from a value lower than the set-
point and check that the trip point remains within the
accuracy described in the data sheet.
• Lo Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the trip point remains within the
accuracy described in the data sheet.
When the setpoints are shifted, please contact M-System’s
Sales Office or representatives.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
